Structural and Electronic Properties of Bulk (2H)-GaSe from First-Principles DFT Calculations with van der Waals Corrections
Julián A. Aros-González, Camilo A. Huertas-Archila, Miguel J. Espitia-Rico
Gallium selenide (GaSe) is a layered III-VI semiconductor whose bulk crystal serves as the essential energetic reference for modeling the isolated monolayer. We present a systemati…
On the development of open geographical data infrastructures in Latin America: progress and challenges
Daniela Ballari, Willington Siabato, Christophe Claramunt +3
Open data initiatives and infrastructures play an essential role in favoring better data access, participation, and transparency in government operations and decision-making. Open…
Modeling of Electromagnetic Radiation using a Dual Four-Potential Representation: From Dipole Blade Radiators to Ribbon Loop-like Antennas
Robert Salazar, Camilo Bayona-Roa
In this paper, we explore classical electromagnetic radiation using a dual four-dimensional potential approach. Our focus is on the Planar Dipole Blade Antenna (PDBA), a syst…
Separability and entanglement in classical eigenfunctions as a criterion for Hamiltonian chaos
A. D. Bermúdez Manjarres
We study the eigenfunctions of the classical Liouville operator and investigate the conditions they must obey to be separable as a product state. We point out that the conditions f…
Zero-Shot Spam Email Classification Using Pre-trained Large Language Models
Sergio Rojas-Galeano
This paper investigates the application of pre-trained large language models (LLMs) for spam email classification using zero-shot prompting. We evaluate the performance of both ope…
Simulation of charged particles in Earth's magnetosphere: an approach to the Van Allen belts
Jorge Enrique García-Farieta, Alejandro Hurtado
Earth's magnetosphere, beyond protecting the ozone layer, is a natural phenomena which allows to study the interaction between charged particles from solar activity and electromagn…
A comprehensive modelling and experimental approach for damped oscillations in U-tubes via Easy JavaScript Simulations
Fredy A Orjuela, Jorge Enrique García-Farieta, Héctor J Hortúa +1
In recent years, science simulations have become popular among educators due to their educational usefulness, availability, and potential for increasing the students' knowledge on…
Exploring the magnetic field of Helmholtz and Maxwell coils: a computer-based approach exploiting the superposition principle
Jorge Enrique García-Farieta, Alejandro Hurtado
Teaching magnetism is one of the most challenging topics at undergraduate level in programmes with scientific background. A basic course includes the description of the magnetic in…
Generalized, sublethal damage-based mathematical approach for improved modeling of clonogenic survival curve flattening upon hyperthermia, radiotherapy, and beyond
Adriana M. De Mendoza, Soňa Michlíková, Paula S. Castro +4
Mathematical modeling can offer valuable insights into the behavior of biological systems upon treatment. Different mathematical models have been designed to predict the efficacy o…
Evaluating a Sigmoid Dark Energy Model to Explain the Hubble Tension
Sergio Torres-Arzayus, Camilo Delgado-Correal, Mario-A. Higuera-G. +1
In this study we analyze Type Ia supernovae (SNe Ia) data sourced from the Pantheon+ compilation to investigate late-time physics effects influencing the expansion history, ,…
CORE -- a COmpact detectoR for the EIC
CORE Collaboration, R. Alarcon, M. Baker +56
The COmpact detectoR for the Eic (CORE) Proposal was submitted to the EIC "Call for Collaboration Proposals for Detectors". CORE comprehensively covers the physics scope of the EIC…
Operational classical mechanics: Holonomic Systems
A. D Bermúdez Manjarres
We construct an operational formulation of classical mechanics without presupposing previous results from analytical mechanics. In doing so, several concepts from analytical mechan…
The Schwinger action principle for classical systems
A. D. Bermúdez Manjarres
We use the Schwinger action principle to obtain the equations of motion in the Koopman-von Neumann operational version of classical mechanics. We restrict our analysis to non-dissi…
Projective representation of the Galilei group for classical and quantum-classical systems
A. D. Bermúdez Manjarres
A physically relevant unitary irreducible non-projective representation of the Galilei group is possible in the Koopman-von Neumann formulation of classical mechanics. This classic…
Unitary representation of the Poincaré group for classical relativistic dynamics
A. D. Bermúdez Manjarres
We give a unitary irreducible representation of the proper Poincaré group that leads to an operational version of the classical relativistic dynamics of a massive spinless particle…
Coulomb Law in the Non-Uniform Euler-Heisenberg Theory
A. D. Bermúdez Manjarres, M. Nowakowski, D. Batic
We consider the non-linear classical field theory which results from adding to the Maxwell's Lagrangian the contributions from the weak-field Euler-Heisenberg Lagrangian and a non-…
Galilean covariance of quantum-classical hybrid systems of the Sudarshan type
A. D. Bermúdez Manjarres, N. Marín-Medina
We revisit quantum-classical hybrid systems of the Sudarshan type under the light of Galilean covariance. We show that these kind of hybrids cannot be given as a unitary representa…
Classical dynamics from a unitary representation of the Galilei group
Andres D. Bermudez Manjarres, Marek Nowakowski, Davide Batic
We give a formulation of classical mechanics in the language of operators acting on a Hilbert space. The formulation given comes from a unitary irreducible representation of the Ga…
Beyond the magnetic field of a finite wire: a teaching approach using the superposition principle
Jorge Enrique García-Farieta, Alejandro Hurtado Márquez
In the introductory courses on electromagnetism, the Biot-Savart law is generally explained by a simple example to find the magnetic field created at any point in space by a small…
